MASSIMAL: A multimodal dataset for coastal habitat mapping in Norway

The MASSIMAL dataset contains data from shallow coastal areas collected using multiple
data modalities, such as hyperspectral and multispectral aerial imaging, underwater
imaging, and sonar measurements. The dataset was collected at four main locations along
the Norwegian coast, in the time period 2021-2023, spanning large variations in habitat
types. The data is organized as a set of ZIP files, with each file corresponding to one
single time, location, and data type. Annotations of hyperspectral images are also
included in the dataset. Potential applications of the dataset include development of
mapping methods for coastal habitats, education on coastal monitoring methods, and
reference material for timeline studies. See README.md and https://github.com/mh-skjelvareid/massimal-dataset for a more
comprehensive introduction to the dataset.
